CONVERTING DEVICE FOR WALL BEDS.

Application filed March 30, 1922. Serial No. 548,127.

To aZZ whom it may concern.

Be it known that I, JAB/[ES A. Moon, a citizen of the United States, residing at Los Angelcs, in the county of Los Angeles and State of California, have invented new and useful Improvements in Converting Devices for Fall Beds, of which the following is a specification.

My invention relates to wall beds, and a purpose of my invention is the provision of a device of extremely simple, durable and efficient construction adapted for converting ordinary bed springs into a folding or wall bed and which is adjustable to accommodate standard forms of spring frames of various dimensions.

Although I will describe only one form of bed spring converting device embodying my invention and will point out the novel features thereof in the claim, it is to be understood that various changes and modifications may be made herein without departing from the spirit and scope of such claim.

In the accompanying drawings,

Figure 1 is a view showing in front elevation one form of bed spring converting device embodying my invention applied to a standard bed spring;

Figure 2 is a vertical sectional view taken on the line 22 of Figure 1, with the converting device and bed in extended position;

Figure 3 is a view similar to Figure 2 with the converting device and bed in folded position;

Figure at is a view similar to Figure 3 showing another form of bed spring and frame in applied position within the converting device;

Figure 5 is a view showing a detailed perspective of one of the standards comprised in the converting device shown in the preceding views.

Referring specifically to the drawings, in which similar reference characters refer to similar parts, my invention, in its present embodiment, comprises a plurality of standards S arranged in pairs adjacent the opposite ends of and secured to the floor F or other suitable support which constitutes the bottom of a wall bed casing designated generally at K. The standards of each pair are formed of relatively short pipe sections provided with flanged bottoms which are screwed or otherwise secured to the floor F. The upper ends of the standards are formed with elbows 16 having their ends arranged bular form so as to slidably receive the secj tions a which are preferably made solid. The sections a may be locked in any adjusted position with respect to thesections (a by means of set screws 18 threaded in the sections a so as to engage the sections a at a point within the former.

The free ends of the sections a and a are provided with brackets or clamps designated at 0 designed to receive the side rails R of a conventional form of metallic spring frame. Each clamp C includes a. stationary jaw 19 and a movable jaw 20, the latter be ing pivotally sustained at a point indicated at 21 upon the stationary jaw to occupyia clamped or released position. A bolt 22 is extended through the free ends of the aws 19 and for maintaining the jaw 20. in clamping position with respect to the other jaw and to thereby securely clamp the rail R therebetween.

' Ears 23 are formed on the uppermost or outermost clamps C, and pivoted to these ears are supporting legs 24 adapted to be held in supporting position by means of arcuate arms 25 recessed adjacent their free ends as indicated at 26 to engage brackets 27 secured to the sections a".

Coil contractile springs 28 are secured t the floor F and to rings 29 embracing the lowermost rail R for counter-balancing the weight of the converting device and bed when moving the latter to extended or horizontal position.

For the purpose of retaining a mattress against displacement from the springs when a bed is in applied position upon the converting device, a cable L is extended between the two pairs of standards S and through sleeves 30 supported on brackets 31 embracing the lowermost rail B. This cable L is also trained through sleeves 32 formed on brackets 33 arranged at opposite ends of the lowermost rail R, and the free ends of the cables are secured to the end portions of the spring supporting frame as clearly shown in Figure 1. The sleeves 30 and 32 are so positioned as to maintain the cable in spaced relation to the arms A and A so as to embrace one longitudinal edge and the ends of a mattress This cable L is adapted to co-operate with mattress clamps 8a for securely retaining the mattress against displacement fromthe spring frame and converting device. The clamps 34L are of standard form and as usual are adjustably associated with the. spring.

In practice, any metallic or wood frame spring of standard construction can be clamped to the arms of the converting device by means of the clamps C, the latter receiving the side rails R of the spring frame-in the manner previously described. It is to be understood that irrespective of the dimensions of the spring frame, that is, within certain limits, the arms A and A can be adjusted to properly position the clamps C- for receiving the side rails R. With, the spring frame secured to the arms, it will be clear that by virtue of the pivotal mounting of the arms, the spring frame is movable from the vertical or folded posi tion shown in Figure 8 to the horizontal or extended position shown in Figure When movingthe converting device from vertical to horizontal position or vice versa, the springs 28 function to counterbalance the weight of the converting device and spring frame and to thereby facilitate the movement ofthe latter. When the bed and converting device is in vertical position, it is completely concealed by a curtain 'l sustained on the top of the casing K in the manner clearly shown in Figure 3..

In Figure 4 I have shown a wooden spring frame associated with the arms of the converting device, and in this adaptation of my invention the movable jaws 20 are moved to open position to permit of the application of screws 37 to the stationary jaws for securing the. side rails of the spring frame to the clamps. It will be noted that the free ends of the stationary jaws l9 are formed with lips 38 which cooperate with the screws in retaining the side walls against movement upon the clamps.

From the foregoing description taken in conjunction with the accompanying drawings, it will be clear that the converting device is capable of sustaining standard forms of'bed spring frames of both metallic and wood construction, and because of the adjustability of the arms it will be obvious that the device is capable of being accommodated to spring frames irrespective of the dimensions. This allows of the use of standard bed spring frames as folding or wall beds, and it eliminates the necessity of providing spring frames of special construction as is now necessary in wall beds heretofore proposed.

I claim as my invention:

in combination, a pair of upstanding tn bular members having inwardly curved u'p 'mr ends, a third tubular member detachably associated with and connecting the upper ends of said member, and a T shaped member having the head thereof rotatahly fitted on the second mentioned member.

in testimony whereof I have signed my name to this specification.

JAMES A. MOON.
